Hello everyone! Many days before i installed XOOPS 2.0.6 in one of my sites(crazyroofs.com) and It was closed for many many days and now i opened it and i have many problems using it...

A friend of mine tried to register and he can't.
I tried to upload my avatar and i can't.
My friend tried to post in forums while i registered him from the admin panel and he couldn't!!

Can somebody help me please
Something gooing wrong! Can't have too many problems! I use XOOPS at many sites and this is the first time i have this problem! Everything is ch-moded right!

Please help me...

(can't ask at xoopsgreece.org cause i'm the owner and i don't know what's happening . It looks like a hacker attacked to my site )

do you (and those of your users having problems) have a software firewall blocking HTTP Referrers?

well i have a firewall but i also had when i uploaded my avatar to my other xoop sites.

Might try this anyway:

can't login and have Norton firewall

Maybe settings or versions differed when you used it before ...
